Title: Improvements in or relating to thermionic cathodes for use in electron discharge tubes
IPC: H01J1/15
Filed: 1939-03-31
Abstract: 527,145. Thermionic cathodes. TELEFUNKEN GES. FUR DRAHTLOSE TELEGRAPHIE. March 31, 1939, No. 10175. Convention date, March 31, 1938. Drawings to Specification. [Class 39 (i)] A directly-heated cathode for magnetrons or other discharge devices has an emissive outer conductor laid over but not completely covering a core conductor, the dimensions and materials of the two parts being such that their resistances per unit length of complete cathode are equal. The outer conductor may consist of one or more wires laid over a core helically or a network of wires drawn over the core. The core may be of circular, flat strip or tubular cross section or it may be two circular parallel wires spaced apart, and it is preferably of tungsten or other metal having a higher melting-point than the overlaid portion, which may be of tantalum or thoriated tungsten. By making the dimensions of the two parts such that they radiate approximately equal quantities of heat per unit length of complete cathode, only very slight temperature differences between any parts of the two components may be achieved. Formulµ are given to show how the two conditions of equal resistance and equal thermal radiation per unit length of cathode are obtained. The two parts may, however, also be such a predetermined temperature difference exists between them, viz. the difference between their softening or emission temperatures. If the core wire participates perceptibly in the emission, the temperature difference between the two parts is made such that the two parts have approximately the same life.

Title: Improved apparatus for operating grabs and the like
IPC: B66C3/10
Filed: 1936-04-17
Abstract: 465,981. Excavators. SOC. FRANCAIS DE CONSTRUCTION DE BENNES AUTOMATIQUES. April 17, 1936, Nos. 11065 and 11066. Convention dates, May 6, 1935 and Nov. 22, 1935. [Class 68 (i)] [Also in Group XXX] A single-chain grab is automatically moved laterally from the loading-point when raised to, and supported by, the usual crown or the like by means of a member which moves in the plane of the hoisting rope and at right-angles to the axis of the hoisting drum. Fig. 4 shows one construction in which the crown 18 is carried by a counterweighted lever 12 pivoted at 11 on a forwardly-projecting crane member 10. Normally the lever 12 is maintained in the fullline position by the hoisting rope 9 engaging the pulley 15, but when the loaded grab is hooked on to the crown, the weight causes the lever to rotate to the dotted line position 12<a>. Further slackening of the hoisting rope in this position then opens the grab. By hauling in the rope 9 to take the main weight of the opened grab, the counter-weight 19 becomes effective to restore the lever 12 to its original position. Fig. 7 shows means for obtaining an increased travel of the pivoted lever 12. The latter is pivoted on an axle 11 that carries a pair of wheels 27 running on tracks 28 fixed to the crane structure. A sector 29 is connected rigidly to the axle 11 and carried a cord 34 connecting it to a fixed point 35. Suspension of the grab from the crown 18 rotates the lever 12 and sector 29. The cord 34 then causes the axle 11 to be displaced bodily into,the dotted line position, the wheels rolling on the track during the process. A second cord 31 passing between a fixed point 32 and point 30 on the sector, assists in the restoring movement of the latter. In Fig. 9 (not shown) the crown is carried by a travelling carriage which runs along rails by gravity when influenced by the weight of the loaded grab. Fig. 14 shows a modification in which the crown 18 is carried by a lever 9 pivoting about the point 55 and connected by links 52 and 53 to fixed points 50 and 51 on the crane structure. The weight of the loaded grab causes the lever 9 to swing about the pivot 55 and in so doing causes the links 52, 53 to swing upwards into positions 52<a>, 53<a>. The loaded grab moves along the dotted line a, b during the process A downward pull on the hoisting line restores the linkage after emptying of the grab. Fig. 15 shows a modification of the latter construction in which the links 52, 53 are practically in alignment in the hoisting position, the crowncarrying lever 54 being vertical. The grab in this case travels along the dotted line a and the lever and links move to the positions 54<a>, 53<a>, 52<a>.
